RUG-DISPLAY RACK.

Application filed January This invention relates to display racks andmore particularly to racks fordisplaying rolled rugs in uprightpositions.

An object of this invention is to provide "1 a rug displayrack in whicha platform is rotatably supported upon a stationary member through theinterposition of anti-fria tion devices, and incorporating means toprevent the operative dislocations of the supporting member androtatable platform when the device is being moved from place to place.

Another object of this invention is to provide my display rack on whichrolled rugs can be supported in upright positions and slightly tiltedtowards the supporting member to aid in stabilizing the rugs in theirsupported position.

A further object of this invention is to n tu able platform comprising`reinforcing means and these reinforcing means also providingrug-receiving recesses for the reception of the lower end of the rolledrugs when in this supported position,

It is also an object of this invention to provide'a rug-display rack ofgenerally improved construction, whereby the device will be simple,durable and inexpensive in construction, as well as convenient,practical, serviceable and efficient in its use.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the com-` i bination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of Y the invention herein disclosed, may be made within thescope of what is claimed, with out departing from the spirit of theinvention. i

The invention has been illustrated in its preferred embodiments in theaccompany.

Referring to the. drawings thereI is shown a stationary member in theform of an annular base 10` having an annular' V-shaped race-way 11formed therein for the reception of anti-friction devicesl or/ ball l2which are held in spaced relation by a spacing ring 13. rlfhe ring 13rides on'i'lat horizontal surfaces 14 formed at the upper edges of therace-way and opposed inner and outer vertically disposed annular flanges15 are formed on the annular base 'lOv and extend upwardly from-the flatsum faces 1a tok form `an annular lubricant receptacle 16. Spaced legs17 extend downwardly from the annular base 10 to provide supportstherefor to enable the `device to be .rigidly supported on a supporting-floor F 1n which there may be, slight irregularities. A hub 18 isformed at the axis of the annular base 10 and is connected to the base10 by radialarms j19, and an axially dis posedaperture 2O is `formedinthe hubl A rotatable member is provided and includes a circularplatform 21` of uniform thickness and having an annular flange 22extending downwardly from the periphery thereof'` The under face of therotatable platform 21 has an annular V-shaped raceway 23 formed thereonand operably engages the balls 12 in order to rotatably support theplatform upon the annular base 10.

lt is highly desirable to have the rotatable platform as light aspossible and therefore peculiar reinforcements are provided in orderthat the entire platform may be cast relatively thin and at same timehave sufficient strength to withstand all stresses to which the devicewould ordinarily bey subjected. To thisend the central portion of theplatform is offset as indicated at 24, and from this point the offsetportion extends radially to the periphery of the platform therebyproviding offset reinforcing ribs or members 25, and opposed arcuaterecesses 26 are formed in the opposed longitudinal edges of the offsetribs 25 to engage the peripheral portions of the rolled rugs R, therebyforming a scat for the lower end of the rugs when placed upright uponthe platform 21.

By this arrangement the entire Lipper surface oi' the platform 21 isformed with a uniform thickness and at the Sametime reinforcements arerprovided which also form seats for the lower end ofthe rugs.

A hub or sleeve 2T is formed at the axis of the platform 21 and this hubreceives a tubulaifshaft 28 which is secured to the hub 2T bytransversely extending' bolts or other lsecuring devices 29, while asupportingmember 30 is carried at the upper end of this shaft. rlrhesupporting member 30 comprises an axial hub 31 suitably secured to theshaft and from this hub radial arms 32 extend, which arms have opposedarcuate recesses 33 formed in the opposed longitudinal edges thereof andthese recesses are in approxivmately vvertical alinement with therecesse 26 formed on the reinforcing ribs 25 of the platform 21. Helicalsprings or other flexible elements 3l are secured to the central portionof the supporting member 30 and engage the peripheral portions of therolled rugs to hold them in their upright positions, the outer ends ofthe springs being detachably secured to lateral extensions 35, formed atthe outer ends of the radial arm 32, by means of hooks or similarsecuring means 36. In order to relieve the springs 34 of someV stress inholding the rings R in their upright position, the opposed recess 26formed in the reinforcing members 25 are spaced further vapart that theopposed recess 33 of the arms 32, thereby causing the upright rugs R totilt slightly towards each as shown in Figure 7, which positionobviously relieves the springs Bllvof considerable stress whilesupporting these rugs and consequently obviates the possibility of therugs falling from their supported position.

A bridge plate 37 is secured to the lower terminal of the platform hub27 by screws or other securing' devices 38 anda threaded axial aperture39 is formed therein for the reception of the threaded end of a bolt orother securing device 40. The Vshank of the bolt l0 is smaller indiameter than the aperture 2O and extends therethrough beyond the lowerface of the base hub 18 and an enlarged head or stop member ll1 isformed at the lower end thereof, which stop member is larger in diameterthan the aperture 20.

In use the plat form is normally rotatably supported upon the base 10 bythe antifriction balls 12, and in this position and the securing deviceLl() does not engage the base member, but merely floats within theaperture 2O of the base hub, so that no friction is created between thestationary base and the rotating platform. However if it is desired tomove the entire raclr from place to place, the platform is then lifteduntil the legs 17 of the base 10 disengage the floor or supportingsurface F. In this position, the enlarged head or stop member -ll of thebolt lO engages the hub f8 of the base 10 and supports the base 10 insuch relation to the platform 21. as to prevent the anti-friction member12 from moving from their housed position between the opposed race-ways11 and 23, which position is shown in Figure 2. Then the rack is againplaced upon the ioor F the head l1 of the bolt llO disenga-ges the basehub 18 and the platform again freely rotates upo'n the balls 12. Thisfeature is highly advantageous in that it permits the rack to be readilymoved about the store without giving attention to the base 10, butprevents friction between the rotating platform and this base when therack is in operating position.

Vhat is claimed as new is:

1. A display rack including a stationary member, a rotatable member,anti-friction means interposed between the stationary member and therotatable member to rotatably support the rotatable member upon thestationary member, a securing device carried by one of the said membersand positioned to engage the opposed member when the rotatable memberhas been moved from operative engagement with the anti-friction meansthereby securing the stationary member to the rotatable member, saidsecuring device arranged to disengage the opposed member when therotatable member operably engages the anti-friction means.

2. A display rack including a stationary member, a rotatable member,anti-friction means interposed between' the said members to operablysupport the rotatable member upon the stationary member, means forpermitting the rotatable member to be moved fromv operative engagementwith the antifriction means, and means for securing the stationarymember to the rotatable member when the rotatable member has been movedfrom operative engagement with the antifriction means.

3. A display rack including a stationary member, a rotatable member,anti-friction means interposed between the said members to rotatablysupport the rotatable member upon the stationary member, and securingmeans for securing the stationary member t'o the rotatable member whenthe rotatable member has been moved from operative engagement with theanti-friction means, said securing means releasing the stationary memberwhen the rotatable member operably enlOO lll)

gages the anti-friction means thereby permitting free rotation of the'rotatable member upon the stationary member.

4. A display rack including a stationary member, a race-Way carried bythe stationary member, a rotatable member, a race-Way carried by therotatable member, anti-friotion devices positioned between the saidrace-Ways to rotatably support tlie vrotatable member upon thestationary member, a securing device carried by one of the s aid membersand extending through an aperture ormed in the opposed member, saidaperture being larger in diameter than the securing device to preventengagement of the securing device with the Wall of the aperture when therotatable member is operably supported by the antiffrction device, and astop carried by the securing device and positioned to engage the memberin which the aperture is formed when the rotatable member has been movedfrom engagement With the anti-ieriction devices, thereby securingl thestationary member to the rotatable member to prevent the displacement ofthe antifiiriction devices relative to the said members.
